I believe there used to be an escort that had something to the effect of "you have to be at least 3 inches to get on this ride" under their avatar.
Some things are in the hands of nature, and not in human control. I get that, and I understand that.
Now many men brag they need a large, when really they don't. Sorry guys.
I always bring 3 sizes to visits: snug fit, regular, and large.
Now I have had both ends of the spectrum with this dilemma. Men that have micro-penis, and men that are packing a third arm.
It is not often enough for me to special order the ultra small condoms or the car covers.
If a man knows he is unusually small or unusually large, should it be his responsibility to bring condoms that fit?
Or since this is our profession, is it our responsibility to be fully stocked?
I will also add, that in many of these situations I feel the man knows he is hard to fit prior to the visit. On several occasions they have tried to use this as a reason for bareback.
